The knock sensor on the 1999-2003 Mazda Protege 2.0L DOHC engine is located on the front of the engine block, just below the thermostat housing. It is a small, black cylinder-shaped sensor with a single wire connector.
Here are some additional details on the location of the knock sensor on the Mazda Protege 2.0L DOHC:
- The knock sensor is located on the driver's side of the engine block.
- It is mounted in a hole in the block, just below the thermostat housing.
- The sensor is held in place by a single bolt.
- The wire connector for the knock sensor is located on the top of the sensor.
If you need to remove the knock sensor, you will need to:
1. Disconnect the wire connector from the sensor.
2. Remove the bolt that holds the sensor in place.
3. Pull the sensor out of the hole in the block.
Be careful not to drop the sensor. It is a delicate instrument and could be damaged if it is dropped.
Once you have removed the sensor, you can inspect it for damage. If the sensor is damaged, it will need to be replaced.
The knock sensor is an important part of the engine management system. It helps to prevent the engine from knocking by adjusting the timing of the ignition. If the knock sensor is not working properly, it can cause the engine to knock and run poorly.
